Black Moons (and more broadly, new moons) have a long history of special meaning in many cultures and practices, and interestingly, it’s often connected to women!

Right off the bat, if you look at a list of lunar deities, you’ll notice that the vast majority of them are female, which is kind of cool and interesting, especially since the moon holds such power in many cultures. In fact, before adopting the modern solar calendar, a lunar calendar was used (and is still used in Islam). All this to say, the man on the moon tends to be a woman, and she has a lot of influence.

But where does the idea of the Black Moon come from?

The answer is pretty mundane: it’s just science, guys. Much like the blue moon, it’s just a colloquial name given to what is, in the grand scheme of things, a fairly mundane celestial event. That said, the idea that the new moon (which includes the Black Moon) is a harbinger of new beginnings comes from many cultures, going back to Ancient Greeks and ancient Pagan practices in Ireland, among many, many others.

In fact, this Black Moon pretty literally ushers in some new beginnings:

"On the evening of October 2, the barely visible waxing crescent moon will shine on Rosh Hashanah, the Jewish New Year. And on October 3, the growing crescent will mark the beginning of Muharram, the first month in the Islamic lunar calendar."
